SG-2003/2003B Mine Natural Fire Bundle Tube Monitoring System

The SG-2003 type mine gas natural fire bundle tube monitoring system is an integrated engineering solution, which is used to continuously obtain the data of landmark gases for underground fires. Through ground monitoring and control, it automatically cycles and samples for analysis to predict and forecast the possibility of fires and gas explosions. This system is composed of underground dust filters, single tubes, primary water filtration devices, distribution boxes, bundle tubes, secondary water filtration devices, vacuum pipeline systems, automatic control cabinets for gas sampling, special chromatographs for bundle tubes, etc. It features a safe and reliable ground analysis and negative pressure acquisition system, an integrated gas sampling automatic control cabinet, flow display and regulation functions, an optimized negative pressure pipeline system, and an automatic check function for resistance-free vacuum pipelines, etc.

1. Safe and reliable ground analysis and negative pressure acquisition system

The analysis center and the negative pressure air source power device are located on the ground; the underground non-electrochemical sensor, the ground electrical equipment does not require harsh riot level requirements, is safe and reliable, and is easy to maintain.

2. Integrated gas sampling automatic control cabinet

The gas sampling system, the flow display and regulation device and the ground secondary water filtration device are integrated into one; the volume is small, the pipeline joints are few, the pipeline is short, and the gas resistance is minimized; the downhole bundle tube to the ground analysis instrument only needs one joint connection, and the installation is simple. Solve the phenomenon that the bundle tube connection in the conventional analysis room is as dense as a spider web.

3. Flow display and adjustment function

Each bundle tube is equipped with a flow display and adjustment device, which can intuitively reflect the working conditions of each bundle tube; measure the flow rate and flow rate of each bundle tube, and accurately determine the advance time of each sample gas analyzed; reflect whether the downhole bundle tube is blocked through flow monitoring, so that the blockage can be dealt with in time.

4. Optimized negative pressure piping system ensures pumping efficiency

The Siemens water ring vacuum pump is adopted, with reliable quality, advanced performance and stability. The design of vacuum pipes such as the intake and exhaust interfaces of the vacuum pump is an effective means to ensure the pumping efficiency. The double vacuum pump switching, automatic check function and emergency bypass pipeline switching function ensure the emergency instantaneous switching of the double pipeline system and reliable operation.

5. No resistance vacuum pipeline automatic check function

This control device works synchronously with the vacuum pump to automatically control the opening and closing of the vacuum pipeline, effectively solving the phenomenon of shutdown backwater and sample gas pollution, maintaining the continuous effectiveness of the second start of the sample gas after a short shutdown; and no resistance and no pressure loss to the vacuum system. Under normal circumstances, even the best mechanical check valve can reduce the pumping efficiency by more than 30%.

6. Engineering solutions that meet customers‘ specific requirements

Provide a special engineering solution with a working surface acquisition distance of more than 10KM and an expansion of the number of monitoring channels to meet the needs of the site.
